INVENTOR WITNESSES I ATTORNEY LESTER SIEBENHAUER, OF SAN FRANCISCO, CALIFORNIA I REMOTE-CONTROL SWITCH.

Specification of Letters Patent.

Patented Apr. 25, 1916.

Application filed February 11, 1913. Serial No 747,711;

T 0 0H whom z't may concern:

Be it known that I, LESTER"SIEBENHAUER, a'citizen of the United States, residing in the city-and county of San Francisco and State of 'Cali'ftmnia, have invented certain new and useful In'i'pi'ovenients in Remote-Control Switches, of'wh'ich the following is a speci fication;

The hereinafter described invention relates to an ii'nproved remote control switch construction adapted to be employed in connection with all switches where it is desired to open the same from a'remote point, as in theaters, stores, oflice buildings or warehouses, in case of fire, and when it is desired to break the electricalconnections for other causes. f

The invention 'has for its principal object to provide a structure which is light in weight, simple in construction, efiicient in all of its operations, and which may be constructed ata less cost than devices of this character now in use.

Another and important object is to provide a switch which after being operated from, a distant point to open and break contact, may be readily reset or closed in the same manner as the common form of knife switch now universally in use is closed.

1 The invention consists in a switch, a trigger for maintaining the same in closed position. electrically controlled means for controlling the operation of said trigger, and means under tension and connected to said switch for opening the same upon the operation of said trigger.

'ith the above mentioned and other objects in view the invention consists in the novel construction and combination of parts hereinafter described, illust 'ated in the accompanying drawings and pointed out in the claim hereto appended.

To more fully comprehend the invention, reference should be had to the accompanying d 'awings, wherein- Figure 1 is a sectional view, taken on the line y-y of Fig. 2 of my invention, with the switch in closed position, disclosing the trig ger, the magnet coil controlling the same,

and the means under tension for opening the switch upon the operation of the trigger. Fig. 2 is a front elevation of Fig. 1 with the magnet coil in section, disclosing the momentary contact switch controlling the magnet coil.

Referring more particularly to the drawings, the reference numeral 1 designates a suitable base of non-conducting material to which is secured suitable plates 52 provided with spring arms 3 adapted to frictionally engage one end of ,fuse plugs l, the opposite ends of which are engaged between other springfingers .5 extending upwardly from plates (3 secured to the base 1, and to said plates are connected the terminals of electric conductors 7. V

Pivotally mounted, as at 8, to the plates 2, are suitable switch bars or blades 9 connected at their ends by a transverse member 10 of insulating material. A switch bar or blade 11 curved at one end, as at 12, is connected at its opposite end to the transverse member 10, and is pivoted within its length, as at 13, to upstandingears l-l, formed at one end of a plate 15, secured to the base 1, and to the opposite end of said plate is connected the terminal of an electric conductor 16. Extending laterally from the sides of the plate 15 adjacent the ears 1!: are lugs or pins 17, to which are connected the lower ends of coiled springs 18, the upper ends of which connect with lugs or pins 19 extending laterally from each side of the upper end of the curved portion 12 of the bar or blade 11, and the action of the springs is to pull the curved portion 12 downwardly, disconnectin g the arms or blades 9 and 11 from the spring contact fingers 20 to which are connected suitable electric transmission wires. Mounted on the plate 15 is a suitable butler 21 adapted to be engaged by the curved por tion 12 of the blade-11 when in its lowern'iost inclined position. A curved brace rod 11 is fastened at its upper end adjacent the upper end of the curved portion 12. and at its lower end to the switch bar or blade 11 to prevent the breaking of the curved portion 12 from the bar or blade 11 when the portion 12 contacts with the buffer 21.

Mounted on the transverse member 10 is an operating handle 22 secured to the member 10 by a shank 23, the end of which projects beyond the end of the handle 22 and is formed on its surface with an inclined notch 2- in which engages the hooked end 25 of a trigger 26 formed on its upper surface with a beveled edge 26 and pivoted as at 27 to a support secured to the base 1, and said trigger retains the blades 9 and 11 in contact with the fingers 20 against the tension of the coiled springs 18.

Pivotally connected to the trigger 26 is the bifurcated end 28 of a rod 29 extending from a core3O of an electro-magnet 31 secured by the screws 32 in a suitable frame or support 33, carried by the base 1, and said core is limited in its movement by a guide 3i secured to the base 1 and adapted to contact with theshou lders 35 formed in the core adjacent the outer'cnd thereof.

The electro-magnet 31 is provided at the rear of the opening in which said core 30 operates with a. screw cap carrying on its inner surface a spindle 36 which is surrounded by and supports a coiled spring 37, the opposite end of which is received in an opening 38 formed in the rear end of the core 30, and said spring is adaptedto push the core 30 outwardly into its normal position as soon as the electro-magnet is decnergized, and restore the trigger to a position to engage the end of the shank 23.

Extending from the electro-magnet 31 are the leads 39 which connect with the contacts $0 of a suitable momentary contact switch, situated at any point desired, and the contacts 40 are adapted to be engaged by spring fingers 41 connected with a vsuitable source of electric energy, when the enlarged head 42 of the operating button 43 passes the enlarged portions 44: at the upper ends of the fingers 41.

Assumlng that the parts are in the posi' tion as disclosed in the drawings, the operation of the device is as follows :Upon the actuation of the momentary contact switch, electric current will flow through the leads 39 and momentarily energize the electromagnet 31, which will draw the core 30 inwardly against the action of the spring 37, and the core in its inward movement will disengage the hooked end 25 of the trigger- 26 from the beveled portion 24 at the end of the shank 23, and the action of the springs 18 will withdraw the bars or. knives 9 and 1 1 from the contact fingers 20 and break the tact therewith.

It is to be understood that various changes 56 in the form, proportion, size and arrangement of the details of construction within the scope of the claim may be resorted ,to without departing from the spirit or sacrificing any advantages of the invention.

Having thus described my invention what is claimed as new and is desired to protect by Letters Patent is A switch comprising a base; stationary contact posts mounted thereon; a curved blade pivoted near the middle of its length to one of said contact posts, one end of said blade being adapted to move into and out of electrical connection with the other contact post; a. handle on the said contactin end of the blade, means for moving sai' blade to non-contacting position comprising a pair of spiral springs symmetrically disposed one on each side of said blade, one end of each of said springs being connected to the pivot-contact-post at a point below said pivot, and the other end of each spring being connected to the outer end of the noncontacting arm of the blade; and a'trussrod joining the two ends of said curved 30 blade.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

LESTER SIEBENHAUER.
